NAME

       bhm - program to send SMTP mail to /dev/null

SYNOPSIS

       bhm [-m maximum-message-size] [-t threads] [-p listen-port] [ -s ] [-a] [-[z|Z] debug-file] [-r reverse-dns] user-list-filename

DESCRIPTION

       This manual page documents briefly the bhm, program.

       It is designed to test the performance of SMTP relay servers by receiving mail to /dev/null at random speeds.

       The  user-list-filename	is the name of a file which contains a list of valid user's email addresses.  The file may have three fields sepa-
       rated by spaces, the email address, the password (used for rabid) and an optional third field to specify what is to be done with the  mail.
       A  'd' character means that it is to be deferred (SMTP 45x), a 'r' means that it is to be rejected (SMTP 55x), a 'b' means that it is to be
       accepted and bounced, and a 'g' means that it is to be grey-listed.

       The reverse-dns file is in the same format as /etc/hosts and gives the value that will be used in the 220 message.  Otherwise  it  will	be
       bhm

       The  maximum-message-size indicates the size in Kilobytes that will be the maximum size of a message that will be accepted.  The default is
       10240k.

       The -s parameter enables SSL.

       The listen-port parameter specifies the TCP port to listen on (default 25).

       The threads parameter is the number of threads that may be created to receive mail.  Note that your BHM machine may have  hardware  and	OS
       limits that determine how many connections it may receive.

       The  -a command turns on all logging.  All message data received will be logged.  This will make it slow and it may not be able to saturate
       a fast Ethernet link...

       The -z switch allows you to specify a debugging file base.  From this base one file is created for each thread (with a ':' and  the  thread
       number appended), each file is used to log all IO performed by that thread for debugging purposes.

       The  -Z	switch is the same but creates a separate file for each connection as well with an attitional ':' appended followed by the connec-
       tion number.

RETURN CODES

       0      No Error

       1      Bad Parameters

       2      System Error, lack of memory or some other resource
